Complete the series. 4, -5,11, -14,22, —

### Explanation

• Here, difference between two consecutive terms is an odd number and there is change in sign of that number also.
• Difference between first pair of two numbers = 1 with change in sign
• Difference between second pair of two numbers = 3 with change in sign
• Same way, difference between third pair of numbers should be 5 with change in sign.
• So, the number becomes, 22 + 5 = 27. With change in sign it will become -27.
